MANUFACTURE OF C "IBON' BISULTID.

specification of Letters Patent.

No Drawing. Applicatlonfiled September at, 1818, erial No. 793.30%. enewed No 7030a.

t chester and State of New York, have invented certain new and useful llmprovements in the Manufacture of Carbon Bisullid of which the following is a specification.

This invention relates to a rocess of man- CS and the subject of the invention consists in improvements to avoid escaping of hydrogen-sulfid which, for instance, is formed in the retort process from the moisture of the sulfur and i l charcoal.

The invention consists in assing the hydrosulfuric gas over or t rough highly heated carbon (charcoal) which may he contained in a retort. The hydrogen sulfid is s m then decomposed and transformed into carbon bisulfid and hydrogen according to the ufacture of carbon bisulfid, the retort for the decomposition of the hydrosulfuric gas may be arranged in the same or in a separate furnace. llt is evident that the out ut of carbon bisulfid is increased by the improved process, and the escaping of sulfur in form of hydrogen sulfid which is a poisonous gas avoided, or at leastefi'ectively decreased.

I claim: 7.

1. The process of generating carbon hisulfid from hydrosulfuric acid (hydrogen sulfid) which consists in passlng the latter through or over highly heated carbon.

2. The process of generating carbon hisul-.

fid from hydrogen sulfid, evolved in a retort which is containing highly heated carbon and fed with sulfur, consisting in pass- All ing the hydrogen sulfid through a .retort which contains highly heated carbon.
